staging: greybus: audio: Initialize sig_bits before configuring hwparams

Browse Source 
Uninitialized variable sig_bits was used while configuring stream params
for codec module. These params are used to configure PCM settings for
APBridgeA.

Usually, this is dependent on codec capability and thus populated via
codec dai_driver definition. In our case, it is fixed to 16 based on the
data format, container supported.
